Once we have been performing continuous exercise<br />
for a period of around 20 minutes, our body reaches<br />
a ‘steady state’. Continuous exercise includes all<br />
forms of exercise that have no stopping periods,<br />
such as jogging, swimming or cycling. Examples of<br />
non-continuous exercise would be weightlifting,<br />
interval training and boxing.<br />
Keyterm<br />
Steady state: when the body is working at a steady<br />
state it means that lactic acid removal is occurring<br />
at the same pace as lactic acid production.<br />
